PHP - Cookie Recall
Hi again all,
I wondered if anyone could help again (sorry). I have one single page which I would like to record a cookie when the user hits submit. The next time the user visits the site, I want it to recall the cookie and put the value in the textbox on the page. I think I have it storing the cookie (not sure though), but I am having trouble getting it to recall in the text box. I wondered if someone could look at this code and see where I am going wrong or help with what I need to add. New to PHP so having trouble getting my head around things. Thanks in advance. Code: [Select] <? setcookie('user',$userName,(time()+60*60*24*30) ); ?> <style type="text/css"> <!-- body,td,th { color: #FFFFFF; } body { background-color: #000000; } .style1 {font-family: Verdana, Arial, Helvetica, sans-serif} --> </style><form id="form1" name="form1" method="post" action=""> <label> <div align="center" class="style1"><strong>My Timetable Search</strong><br /> <br /> Enter Network User ID:<br /> <input type="text" name="txtUserID" id="txtUserID" value=""/> </div> <p align="center"> <label> <input type="submit" name="cmdGo" id="cmdGo" value="Show Timetable" onclick="setcookie('user',$userName,(time()+60*60*24*30);"/> </label> <br /> </p> <hr /> </form> <div align="center"> <?php $userName = $_POST["txtUserID"]; $hostname = "xxxxx"; $dbuser = "xxxxx"; $dbpassword = "xxxxxx"; $dbname = "xxxxx"; $LessonCount = 0; $db_link=mysql_connect($hostname, $dbuser, $dbpassword) or die("Unable to connect to the server!"); mysql_select_db($dbname) or die("Unable to connect to the database"); $fields_array=array(); $num_fields=0; $num_row=0; $sql= "SELECT core.UserID, wstt.Period, wstt.Lesson, wstt.Staff, wstt.Room FROM wstt INNER JOIN core ON wstt.Adno = core.Adno WHERE core.UserID='$userName'"; // find position of "FROM" in query $fpos=strpos($sql, 'from'); // get string starting from the first word after "FROM" $strfrom=substr($sql, $fpos+5, 50); // Find position of the first space after the first word in the string $Opos=strpos($strfrom,' '); //Get table name.

What im trying to do is to recall the list of bad words from my database and if some of them is going to be displayed they should replace it with :-x well I made the `$bwords` to recall the info from the database. OK, When the user fills the info in the form out it goes in the DB fine. I can then array them on the "showroom page" fine. When they upload a picture it goes into the /images/ folder fine. Problem is... On each array on the showroom page I need the image they uploaded to be displayed. Cant work it out. Help would be GREAT!!!!! I have learned php coding by doing (looking for patterns and trying things) and I have hit a roadblock trying to modify a template that creates a delimited text file of products from an ecommerce site (Sunshop) for upload to google base. I have tried to search for the answer but I don't know what I don't know so I may not have put the right search terms in. So I apologize if this has been addressed in the past. The script uses case to call up the contents of specific rows of the product table which I understand but in when I want to call up the manufacturer row Sunshop uses a reference number and then a different table called manufacturers with an ID row that matches the manufacturer row numbers (that are associated with each product) and then next to it a name row which contains the actual manuracturer names. Can I put code in the case that will pull up the referenced name as opposed to just the numbers that are in the column? This is what I have now that just calls up the cells from the manufacurer row: Code: [Select] case 'mfg': $item[mfg] = $item[manufacturer]; The mfg refers to this part of the code in an array: Code: [Select] array('header' => 'manufacturer', 'value' => 'mfg'), In case it helps I will attach the full document. Thanks. I have a question about cookies I want the cookie to work on all the paths / folders / directorys located in a root path. So say like.. http://www.site.com/members/login.php is the folder which sets the cookie, then this cookie will also work on like.. http://www.site.com/bla/boo/works.php I'm trying to do: setcookie(Data1, 'valueofthecookie', '/', '.site.com', 1); But its not working... i want to store the nickname of the user as a cookie.. somthing like set cookie name=nickname,value=smarty,expires after 1 week i know cookies are stored against domain names. what happens when another person logs in the same computer, with different login, and his nickname is diff how does the cookie get handled, and how does the right nickname flash against the right persons login id... Hi, I was trying to use setcookie on my website but when I try to use, it wasn't setting anything and then I tried to make sure if it's setting something, I added Code: [Select] echo $_COOKIE;But it shows Array (just the word) instead of tblogvalue. This is the code I'm using; Code: [Select] $Month = 2592000 + time(); setcookie(tblog, tblogvalue, $Month); echo $_COOKIE; Ok I have my login form and previously I was using $_SESSION untill I learned this removes data when browser is closed. Someone said to me to use cookies but I have no clue where to begin on setting a cookie or reading information from it. Can anyone point me to a tutorial on cookies? I have part of my script that I have used many times in many diffrent applications that works just fine. But in this use it refuses to set the cookie or do anything besides the redirect for that matter. // if login is ok then we add a cookie $ip = $_SERVER['REMOTE_ADDR']; $datem = date("j F Y, g:i a"); mysql_query("UPDATE YBK_Login SET date = '$datem' AND ip = '$ip' WHERE ID = '{{$info['ID']}'")or die(mysql_error()); $_POST['username'] = stripslashes($_POST['username']); $hour = time() + 3600; setcookie('ID_WatsonN', $_POST['username'], 0); setcookie('Key_WatsonN', $_POST['pass'], 0); setcookie('UID_WatsonN', $info['ID'], 0); setcookie('LOGIN', $info['ID'], time()+3); //then redirect them to the members area Header("Location: dashboard.php"); how can i set cookie like a*dm*n@**t*r*c**.*c** ?? Code: [Select] $cookkiee = $islem_1['mail'] ; $sayisi = strlen($cookkiee)-1 ; $cok = $islem_1['mail'] ; for($i=0;$i<=$sayisi;$i++) { $sifr = rand(0,2); if($sifr ==0) { $cok[$i]= '*'; } $dizik = $cok[$i]; setrawcookie("kayip",$dizik,time()+(60*30),"/"); $_COOKIE['kayip'] = $dizik; echo $dizi // etc . a*dm*n@**t*r*c**.*c** } echo $_COOKIE['kayip']; // etc. just one char being like random a Hi all, I'm struggling with a program I'm trying to write with cookies, so any help would be very much appreciated!! What I'm wanting to do is when someone visits my site, I want to display content until the end of the day, and once the days up it disappears forever/until the cookies are deleted. Could someone help me with this? Thanks lots in advance, Jake if a user clicks ?hide=1 or ?hide=2 it does Code: [Select] if (isset($_GET['hide'])){ $id = intval($_GET['hide']); setcookie('hide', ''.$id.'',time()+32000000); header('Location: index.php'); exit; } How do I make it so if they click ?hide=1 it ad's 1, but what if they do ?hide=2 also? it would need to be 1,2 not just 2. Hey PHPFreaks! I have a problem with my login script, because when i login it sets a cookie and it all works. But when i got redirected and refresh the page, my script turns an error which says i'm not logged in? how come? This is what finds the cookie and redirects me Code: [Select] if(!isset($_SESSION['auth']) && !isset($_COOKIE['authcookie'])) { $_SESSION['ERROR'] = 7; header('location: index.php?login'); } When a cookie expires what happens to it? Is it physically removed from your hard-drive? TomTees This topic has been moved to Miscellaneous. http://www.phpfreaks.com/forums/index.php?topic=346675.0 Hello All I wrote a tiny piece of cookie code (to set and record cookies and hits) that works pretty well but seems to have a bug in it that I cannot figure out. First, here is the code: Code: [Select] <?php $my_cookie = (isset($_COOKIE['my_cookie'])) ? true : false; $countFile = "./data/count.txt"; $cookieFile = "./data/cookie.txt"; $dateTime = date('Y-m-d\,H:i:s\,U\,T\,O\G\M\T'); $remoteIPAddress .= $_SERVER['REMOTE_ADDR']; $remoteUserAgent .= $_SERVER['HTTP_USER_AGENT']; $cookieVal = $dateTime; $cookieVal .= ","; $cookieVal .= $remoteIPAddress; $cookieVal .= ","; $cookieVal .= $remoteUserAgent; $cookieVal .= "\r\n"; if(!$my_cookie){ // read the visit counter $countHandle = fopen($countFile, 'r'); $visitCount = intval(trim(@fread($countHandle, filesize($countFile)))); fclose($countHandle); // incremenet the visit counter $visitCount++; // write the new visit count and cookie value to their respective files $countHandle = fopen($countFile, 'w'); $cookieHandle = fopen($cookieFile, "a+b"); if(!preg_match('/bot/',$remoteUserAgent)){ fwrite($countHandle, $visitCount); fwrite($cookieHandle, $cookieVal); } fclose($countHandle); fclose($cookieHandle); setcookie("my_cookie", $cookieVal, time()+31556926); } else{ // read the visit counter $countHandle = fopen($countFile, 'r'); $visitCount = fread($countHandle, filesize($countFile)); fclose($countHandle); } ?> What is happening is that sometimes, not every time, but, sometimes my cookie.txt count gets a 0 (zero) written back to it and I can't figure out why. Can anybody see anything in there that would have this effect? Like I said, it only gets zeroed out from time to time. Thanks to all for taking the time to read. I have an array of fields: $fields = array( "cfg_change_date" => "Configuration Change Date", "system_name" => "System Name", "system_manf" => "System Manufacturer", "system_model_no" => "System Model Number", "system_serial_no" => "System Serial Number", "system_board_part_no" => "System Board Part Number", "system_board_serial_no" => "System Board Serial Number", "asset_tag" => "Asset Tag", "sla_code" => "SLA Code", "category" => "Category", "os_version" => "OS Version", "os_upgraded" => "OS Upgraded", "bios_version" => "BIOS Version", "bios_upgraded" => "BIOS Upgraded", "ilom_version" => "ILOM Version", "ilom_ip" => "ILOM IP Address", "ilom_updated" => "ILOM Updated", "rack_id" => "Rack ID", "rack_location_id" => "Rack Location ID", "tech_id" => "Tech ID", "warranty" => "Warranty" ); I have them all outputted as checkboxes right now in a form. When the user hits save, I want the checked ones to be stored in a single cookie and then later referenced so it remember what the user wants to query from the DB. The thing I cant figure out is how to do this dynamically rather than checking if each one is checked. How can I use a cookie to pull data from my db. Right now I have it set up to pull data from a session variable, but I need it to be able to display data from both since I am implementing a remember me checkbox on my login. Current Code: $q = mysql_query("SELECT `firstname`, `lastname`, `firstname`, `lastname`, `email`, `entrepreneur`, `investor`, `companyname`, `companywebsite`, `founder`, `phone`, `address`, `city`, `state`, `zipcode`, `country`, `development`, `capitalamount`, `companydo`, `founderbuilt`, `understand`, `competition`, `money`, `demo`, `incorporation`, `companynameinv`, `phoneinv`, `addressinv`, `cityinv`, `stateinv`, `zipcodeinv`, `countryinv`, `angel`, `vc`, `capital` FROM `users` WHERE username= '" . $_SESSION['username'] . "'"); $r = mysql_fetch_assoc($q); if (!isset ($_GET['u'])&&($_SESSION['username'])||($_COOKIE['username'])) { echo "blahblah" Hi All, I have a secure website which always checks the cookies is not expired and the session id is set. When someone doesn't browse for the period of the cookie it will expire however the session id stays valid until he logout. A lot of people don't logout so the pages will still be accessable for them or others who use their pc. Is there a way to destroy the session id when the cookies expires? Marco Hello, My latest issue is with a login page I am trying to set a cookie for. I have deduced that it it pulling my info out of my database correctly. It does not give any errors for username or password when they are entered correctly but when I get to the end of the script where I would like to set a cookie and redirect to a new page it just stays on the same page and appears as if it is loading but nothing happens. After I stop the browser and attempt to reload the page it gives me an error saying the page cannot be displayed. Do I need to specify anything before I can have the following code work or is it that it is clashing somewhere else along the way? Code: [Select] <?php else { // if login good set cookie $_POST['username'] = stripslashes($_POST['username']); $hour = time() + 3600; setcookie(ID_my_site, $_POST['username'], $hour); setcookie(Key_my_site, $_POST['pass'], $hour); //then redirect them to the members area header("Location: http://example.com/"); die(); } ?> If I remove this code and simply leave the redirect as shown above, it works. But that defeats the purpose of the script as on the redirected page there has to be a cookie set to display it. Any help would be appreciated I see all over the web that I should tie a session cookie to an ip to help stop some XSS session stealing, but I can't find HOW to do this anywhere. Can someone post some example code? Thanks! |
